Solubility and Factors Affecting Solubility starts at 9 and continues till grade 12. QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Solubility and Factors Affecting Solubility. How you perform is determined by your score and the time you take. When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.

Define the term 'like dissolves like' in the context of solubility.

Describe the effect of common ion on the solubility of a sparingly soluble salt.

Describe the relationship between solubility and temperature for most ionic solids.

Explain how pressure affects the solubility of gases in liquids.

Explain why increasing temperature decreases the solubility of gases in water.

Explain why NaCl is more soluble in water than in hexane.

Explain why sugar dissolves faster in hot water than in cold water.

Explain why the solubility of Na₂SO₄ decreases with increasing temperature above 32.4°C.

If 20 g of a salt dissolves in 50 g of water at 30°C, what is its solubility in g per 100 g water at this temperature?

If 36 g of NaCl dissolves in 100 g of water at 25°C to form a saturated solution, what is the solubility of NaCl at this temperature?

If the solubility of a gas at 1 atm is 0.5 g/L, what will be its solubility at 3 atm (assuming temperature is constant)?

State Henry's Law.

State the effect of temperature on the solubility of exothermic dissolution processes.

The solubility of a salt in water at 20°C is 36 g per 100 g water. If 50 g of the salt is added to 100 g water at 20°C, how much will remain undissolved?

The solubility of KNO₃ in water at 60°C is 110 g per 100 g water. If you add 120 g KNO₃ to 100 g water at 60°C, how much will remain undissolved?

A saturated solution of CaF₂ is prepared at 25°C. If the K_sp of CaF₂ at this temperature is 3.9 × 10^-11, calculate the molar solubility of CaF₂ in water at 25°C.

A saturated solution of PbI₂ is in equilibrium with its solid at 25°C. If some solid KI is added to the solution, what will happen to the solubility of PbI₂? Explain your answer.

A solution is prepared by dissolving 2.0 g of a non-volatile, non-electrolyte solute in 100 g of water at 25°C. If the vapor pressure of pure water at 25°C is 23.8 mmHg, and the vapor pressure of the solution is 23.5 mmHg, calculate the molar mass of the solute. (Assume ideal behavior.)
